Cans Can Roll


Broad Question:

How will the can roll at different angles?


Specific Question:

How far will the can roll at angles of; 120 degrees, 140 degrees and 160 degrees?


Variables:

Independent Variable:

Angle


Dependent Variable:

Distance (CM's)


Variables That Need To Be Controlled:

  • Same person
  • Same can
  • Same room/floor
  • Same materials
  • Same measurement

Hypothesis:

I hypothesize that the can will roll will roll the smaller degrees.

Experimental Design:

I will be conducting my experiment in the basement of my house. My father and I will be testing. My father will be measuring the amount of electricity that will be needed to power the electronics. I will be pedaling the bike that will be used to generate the electricity. Their will be five trials for both group of electronics. I will be putting the data directly onto to the computer, so I won’t lose anything. Once I get everything together, I will then hook up the first set of electronics to the bike, then the next set. I will record the data and put it on my Science Fair Wiki page, take pictures of my materials and my poster board and record all of the project details and information.

Materials List:

  • Exercise bike
  • Small T.V.
  • FM Radio
  • VCR
  • Extension wire
  • Killa-Watt Watt Measurer

Detailed Procedure:


1. Get materials needed to perform the experiment.

2. Connect everything into proper positions.

3. Pedal bike and see if the minimum electricity needed to power the electronics can be reached.

4. Record how many watts is needed to power the electronics (T.V. & VCR) do this five times.

5. Move on to the next set of electronics. (Radio)

6. Repeat steps 3 & 4.

7. Record all data onto the data table.

8. Upload photographs to computer and send to teacher.

Background Research:

Source #1: Stationary bike can generate a descent amount of electricity. Small motor can generate light bulb. A bigger motor means more power and electricity.
Source #2: A bike with enough power is able to generate a T.V., blender, VCR, and any electronic in that range and below. Tunturi or Vitamaster bikes are preferred if I want to generate the right amount of electricity to power what I need.
Source #3:
  • Push the pedals on the bike to begin cycling.
  • Note how many rotations per minute you are turning the flywheel on the bike.
  • Multiply the resistance you utilized by the length of the flywheel. For stationary bikes, the flywheel is typically 6 meters, or 19.7 feet, in length. Let's assume the resistance you are using is 0.5 kg or 1.1 lb. So 6 meters x 0.5 kg = 3.0 kg meters.
  • Multiply the step 4 number by your rotations per minute to get how much power your are generating per unit of time. Using the example in step 4 and assuming an RPM of 100 then 3.0 kgm x 100 rotations per minute equals 300 kgm per minute.
  • Multiply your kilogram meters per minute value by 0.164 to convert it to watts, which is the traditional way of expressing power output. For instance, 300 kpm per minute x 0.164 = 49.2 watts.
  • Voltage-The force that makes electrons move in an electric current. It is produced by a source of electrical energy, such as a battery. Electrical Energy-The energy of moving electrons, as in an electrical current that flows through a wire connected to a battery.
